Unless the guy who is posting the pirated PDF downloaded it from a shady site that inserts PDF viruses and whatnot. The point is, it's neither ethical nor safe to use this pirated copy. One of the authors, Evi Nemeth, was a really great and interesting person who I've heard speak at conferences. She also co-wrote the Linux Administration Handbook, which I read both editions years ago, so I can vouch for their quality. However, as computer books are most likely to do, they are quickly made out of date by the rapid pace of linux development (even Enterprise linuxes like CentOS). I learned my trade mostly through doing, watching other people do things, reading lists, and attending conferences, Linux Users Groups and other meetings of Linux admins. I love books, and continue to buy reference books for languages and favorite software tools, but I don't have any recent Linux books. -- Jonathan Billings <billings@xxxxxxxxxx> _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
